[RFC PATCH v6 16/43] arm/p2m: Cosmetic fix - substitute _gfn(ULONG_MAX) for INVALID_GFN

[Rose.Spangler@xxxxxxxxxxxxxx]

From: Sergej Proskurin <proskurin@xxxxxxxxxxxxx>

In ./xen/arch/arm/p2m.c, we compare the gfn's with INVALID_GFN
throughout the code. Thus it makes sense to use the macro INVALID_GFN
instead of a hard coded value to initialize "p2m->lowest_mapped_gfn".

This is commit 5/12 of the altp2m_init/altp2m_teardown routines phase.
